LEATHER GUIDE / TANNERY
ECCO LEATHER
Respecting tradition, crafting new leather.
The appearance of the material, the tactile sensation, and the craftsmanship behind it.
We introduce the leather-making process of ECCO LEATHER, a supplier adopted by ITTI.

01 / ECCO LEATHER
Leather born from design and technology.
ECCO LEATHER is a leather manufacturer that develops and produces leather against the backdrop of the shoe manufacturer ECCO. While cherishing traditional leather-making techniques, they are also committed to new finishes and manufacturing methods.
A wide variety of leather textures and feels are born from an environment where designers, researchers, and leather technicians explore materials together. At ITTI, we focus on their texture and commitment to craftsmanship, incorporating them into our bags and small leather goods.

02 / INNOVATION
A new perspective on the manufacturing process.
In addition to pursuing the texture of leather, ECCO LEATHER is also working on technology development to reduce the water, chemicals, and wastewater used in the manufacturing process. One such technology is their proprietary DriTan™ technology.
DriTan™ is a technology that utilizes the moisture naturally contained in raw hides during one of the tanning steps, reducing the amount of additional water used. Among the materials adopted by ITTI, it is used in RAPTO FLEX.

Shrunken leather with natural grain, and smooth leather with a polished look. Even leathers from the same manufacturer have different textures.

04 / CHARACTER
Embracing natural expressions as individual character.
Natural leather varies in grain size, wrinkles, and skin texture. The fact that the appearance changes depending on the part used is a unique characteristic of leather.
At ITTI, we incorporate each leather into our products while considering both the characteristics of the material and the appearance of the finished item. Please enjoy these non-uniform textures as the individual personality of each piece.
